I just wish every programmer completed the rustlings game/tutorial. Doesn't take that long.
I didn't even fully complete it, and it made me a way better programmer, because it forces you to think RIGHT.
It may sound weird for people who haven't experienced it, but it's amazing when you get angry at the compiler and you realise... It is right, and you were doing something that could f*ck you up 2 months in the future.
And after a bit of practise, it starts wiring your brain differently, and now my Python code looks so much better and it's way more safe just because of those days playing around in rustlings.
So yeah, Rust is an amazing language for everything, but particularly for kernel development. Either Linux implements it, or it'll probably die in 30 years and get replaced with a modern Rust kernel (Redox OS?).
